One of the best sights in Korça is this tiny, quiet chapel in a village just east of town. This magnificent 14th century Byzantine church is painted with brightly-coloured frescoes that UNESCO specialists describe as being among the best in the Balkans. In the narthex, the entrance hallway, note the Day of Judgement fresco which shows a dragon swallowing sinners in a river of fire, above some vivid illustrations of what happens to sinners and non-believers; devils gleefully ride atop people, wrench off noses, drill holes into heads and span people in front of ploughs... believe or burn! Unfortunately some frescoes are damaged by ignorant  tourists and electricians. Serious art lovers should bring a flashlight to illuminate details in the dark interior.
The church can be found in the centre of Mborja. Follow the signs out of town past the brewery and the George hotel to Mborja; the church is in the village centre, a 20 minute walk uphill from central Korça. If the church is closed, ask around for the key.
